VFA (Volatile Fatty Acids)

Volatile Fatty Acids (VFAs) are short-chain fatty acids produced when microorganisms break down organic matter, such as plant material or waste, during fermentation processes. They are key energy sources for some animals and play a vital role in the digestion system, especially in ruminants like cows. Common VFAs include acetic, propionic, and butyric acids. They are also used in industrial applications, such as biofuel production. Monitoring VFA levels helps assess fermentation efficiency and overall health of microbial ecosystems in processes like wastewater treatment and animal digestion.
